Abstract (in Japanese) (See Japanese page) 
(in English) Many natural phenomena exhibit quasi-periodic fluctuations in appearance. Quasi-periodic signals can be analyzed more accurately using feature points than methods that focus on simple periodicity. The topology method is one of the methods for accurately estimating the interbeat interval of the heart from millimeter-wave radar signals. This method uses topology correlation, which indicates the similarity between waveforms based on feature points calculated from skin displacement, to detect reliable adjacent displacement waveform pairs and achieve high accuracy. In this study, we discuss the method of assigning feature points used in topology correlation calculations in order to estimate the interbeat interval for a wider time interval.
